Chemical pinching of Chrysanthemum x morifolium Ramat. with undecanol
… applied as foliar sprays were effective in pinching most varieties of chrysanthemum tested. Cultivars varied in their response. Subapical phytotoxicity increased with increasing concentrations and was generally more variable among cultivars than was the pinch response. Concentrations …

Pinching and Spacing Effects on Cut Sunflower (Helianthus annuus) Production in East Texas
<p>Three experiments evaluated pinching and spacing on <em>Helianthus annuus </em>in East Texas to determine their effects on growth and development. Experiment 1 was designed to determine the effects of pinching nodes 1, 2, 3, or 4 on ‘Pro Cut Gold’ sunflowers. Results from experiment 1 showed …

Effects of mulching, pinching, and vine spreading on production of fresh market tomatoes
… growing seasons to test the effects of mulching, pinching, and vine spreading on production of groundgrown, fresh market tomatoes. Pinching out the apex of tomato plants 7 days after field setting in 1971 delayed fruit harvest but did not affect total yield or fruit quality. Pinching gave no …

Analysis of Memristor Hysteretic Systems: A Hybrid Coupled Model with emphasis on Pinching/Degrading Behavior
This thesis proposes a novel model that accurately captures the asymmetric hysteretic behavior of memristive devices exhibiting self-crossing hysteresis loops. The proposed model combines the Bouc-Wen Baber-Noori model with other non-linear elements in the resistive switching process. Existing …

EFFECT OF PINCHING AND SPACING ON THE GROWTH AND DEVELOPMENT OF SUNFLOWERS (HELIANTHUS ANNUUS) IN EAST TEXAS
… grown in East Texas to evaluate the effect of pinching and spacing on their growth and development. The first experiment was conducted twice (Trial 1A, 28 April 2017 and Trial 1B, 3 August 2017) to evaluate the effect of pinching at nodes 1, 2, 3, and 4 on sunflower cultivars ‘Superior Gold’, …

The effects of photoperiod, pinching, and plant growth regulators on growth and flowering of Abutilon x hybridum
… the height of nonpinched plants. Chemical pinching agents, including mefluidide and Atrinal, induced more lateral branch development and increased flower production of both seed-grown and cutting-grown plants. As the concentration of mefluidide and Atrinal increased, so did the number of …

Regulation of Growth and Branching of Containerized Penstemon x mexicali Cultivars
… analyze the effects plant growth regulators and pinching practices have on the growth habit of Penstemon x mexicali Pikes Peak Purple and Red Rocks and to produce more marketable containerized Penstemon. A preliminary study analyzed the effects branching agent PGRs had on Pikes Peak Purple. We …

Use of Plant Growth Regulators to Increase Branching of Clematis Spp.
… the vine during production. Cutting back, or pinching, of a plant is labor intensive and compromises bloom for vegetative growth at time of sales. The purpose of this project was to eliminate manual pinching by treating young plants with chemical plant growth regulators (PGRs) that enhance …

Rheology and Processing of Animal and Plant-Based Dense Emulsions
… power law exponent governing the intermediate pinching dynamics is similar to the exponent obtained from the shear flow curve, the terminal pinching dynamics show strong local effects, influenced by interstitial fluid properties, finite drop size, and capillarity

Nonlinear evolution of annular layers and liquid threads in electric fields
… in these two regimes. It is found that jet pinching does not occur irrespective of the parameters, Regimes are identified where capillary instability leads to the formation of stable quasi-static microthreads (connected to large main drops) whose radius decreases with the strength of the …

Computed Nonlinear Seismic Response of Reinforced-Concrete Wall-Frame Structures (Dynamic, Analysis)
… of wall members as well as the effects of pinching action and strength decay of coupling beams on overall computed responses of the coupled shear wall structures are discussed.

Innovative Platform Design for In Vitro Primary Blast Injury Research
… Each bridge wire was inserted into the SWG via a pinching mechanism. Either side of the pinching mechanism was connected to either terminal of the capacitor. When the pulsed power generator was cycled, the bridge wire was vaporized and generated a shock wave. A piezoelectric sensor near the wide …

Incorporation of tropical cyclone avoidance into automated ship scheduling
… masses, while near-shore scenarios examine the pinching effect of TC landfall. Shorter distances are traveled by CLF ships in the scenarios when the TC obstacle is forecasted, but the present position is excluded. The recommended TC representation is the 24-hour advanced position, with no …

Monotonic and Cyclic Simulation of Screw-Fastened Connections for Cold-Formed Steel Framing
… a nonlinear hysteretic model that can simulate pinching and strength and stiffness degradation consistent with CFS screw-fastened connections. The user element is verified at the connection level, including complex cyclic deformation paths, by comparing to OpenSees connection simulation results. …

Functional Connection Between Yeast Dynamin and Retromer at the Endosome
… to localize at the endocytic sites to promote pinching off of endocytic vesicles. The goal of this study was to further investigate the relationship between the Retromer and Vps1. My data show colocalization between Vps1 and the Retromer, and that Vps1 knockout cells show a decrease in Retromer …

Multi-touch through-the-lens drone control
… shot. The four gestures we support are dragging, pinching, two finger rotation and two finger drag. The feedback consists of the live feed from the camera, as well as a preview of the image transformation that was indicated. When the user lifts their fingers, the commands are sent to the drone so …

Thin-walled composite deployable booms with tape-spring hinges
… The folding simulation includes the effects of pinching the hinge in the middle to reduce the peak moment required to fold it. The deployment simulation fully captures both the steady-state moment part of the deployment and the final snap back to the deployed configuration. An alternative …
